I've been trying to figure this one out for a couple of days now. When ever I log into gnome I keep getting this error, I've tried adding my hostname to 127.0.0.1 in the /etc/hosts file but no change. I'm running an Athlon XP with a G3 Ti200. Any ideas???

So I changed my XF86config file wich had /dev/cua0 as the mouse, to to /dev/ttyS0, and bingo! Now it seems that Gnome is able to resolve my hostname, and performance has greatly increased as well. I never thought a mouse could cause such an problem. Now I can finally finish setting my client.
